Beyond “Train to Busan”: Underrated Korean Zombie Web Series You Need to Watch
Korean zombie cinema exploded onto the global stage with the visceral thrill ride that was “Train to Busan.” Its fast-paced action, compelling characters, and poignant social commentary captivated audiences worldwide. While “Train to Busan” undoubtedly deserves its acclaim, the Korean entertainment industry offers a wealth of equally compelling, yet often overlooked, zombie content, particularly in the realm of web series. These series, often shorter and more experimental than their feature film counterparts, provide a unique window into the Korean perspective on the undead, exploring diverse themes and pushing the boundaries of the genre. This article delves into some of the most underrated Korean zombie web series that deserve a place on every zombie enthusiast’s watchlist.

1. Kingdom: A Historical Horror Epic
While technically a Netflix original series, and therefore arguably not strictly a “web series” in the traditional sense, Kingdom deserves immediate inclusion due to its initial streaming-based release and its profound impact on the Korean zombie genre. Set in the Joseon dynasty, Kingdom blends historical drama with relentless zombie horror. Crown Prince Lee Chang, framed for treason, embarks on a perilous journey to uncover the truth behind a mysterious plague ravaging the kingdom. This plague transforms the infected into ravenous, flesh-eating monsters, forcing Lee Chang to not only fight for his survival but also to protect his people from both the undead and the political machinations of the royal court.
Kingdom‘s brilliance lies in its masterful world-building. The series meticulously recreates the Joseon era, showcasing its intricate court politics, social hierarchies, and traditional customs. The juxtaposition of this historical setting with the modern horror of a zombie outbreak creates a unique and unsettling atmosphere. The zombies themselves are particularly terrifying, their movements fluid and aggressive, and their hunger insatiable.

Beyond the horror, Kingdom explores themes of political corruption, social inequality, and the responsibility of leadership. Lee Chang’s journey is not just about survival; it’s about learning what it truly means to be a king and fighting for the well-being of his people. The series also features strong female characters, who challenge traditional gender roles and play crucial roles in the fight against the undead. The production value is exceptionally high, with stunning cinematography, elaborate costumes, and impressive special effects. Kingdom is a must-watch for anyone who enjoys historical dramas, zombie horror, or simply well-crafted storytelling. The series boasts two seasons and a special episode, “Kingdom: Ashin of the North,” which delves into the origins of the zombie plague.

2. Sweet Home: A Monster Apocalypse with a Psychological Twist
Sweet Home, another Netflix original based on a popular webtoon, presents a unique take on the zombie genre. Instead of a widespread outbreak, the series focuses on a group of apartment residents trapped inside their building as monsters begin to appear. These monsters aren’t created through a typical viral infection; instead, they are manifestations of people’s deepest desires and darkest fears.
Cha Hyun-soo, a reclusive high school student who recently lost his family, moves into the Green Home apartment complex. Soon after, a mysterious phenomenon sweeps the nation, turning people into grotesque and violent monsters. Hyun-soo, along with his fellow residents, must fight for survival against these creatures while also grappling with their own inner demons.
Sweet Home stands out for its creative monster designs, which are often both terrifying and strangely beautiful. The series delves into the psychological toll of the apocalypse, exploring themes of isolation, trauma, and the struggle to maintain humanity in the face of unimaginable horror. Hyun-soo’s character arc is particularly compelling as he grapples with his own monstrous tendencies and discovers a unique ability that could be the key to saving humanity.
The series features a diverse cast of characters, each with their own secrets and motivations. The relationships between the residents of Green Home are complex and often fraught with tension, but they are also forced to rely on each other for survival. Sweet Home is a visually stunning series with impressive special effects and a haunting soundtrack. It’s a must-watch for anyone who enjoys monster movies, psychological thrillers, or stories about overcoming adversity.

3. #Alive: A Social Media-Savvy Zombie Thriller
While technically a film and not a web series, #Alive deserves a mention due to its close ties to the web series format and its focus on the digital age. It offers a compelling and relevant perspective on the zombie apocalypse in the age of social media and internet dependence. Oh Joon-woo, a young gamer and streamer, wakes up one morning to find his apartment complex overrun by zombies. Trapped inside his apartment with dwindling supplies, he relies on social media to connect with the outside world and document his struggle for survival.
#Alive explores the themes of isolation and disconnection in the digital age. Joon-woo’s reliance on social media initially provides him with a sense of connection and purpose, but it also highlights his vulnerability and isolation. The film effectively portrays the chaos and misinformation that can spread during a crisis, as well as the power of online communities to offer support and hope.
The film’s pacing is tight and suspenseful, and the zombie action is intense and visceral. Yoo Ah-in delivers a strong performance as Joon-woo, portraying his character’s fear, desperation, and eventual resilience. Park Shin-hye also shines as Kim Yoo-bin, a resourceful survivor who lives in a neighboring apartment complex. #Alive is a relevant and engaging zombie thriller that offers a fresh perspective on the genre. It’s a must-watch for anyone who enjoys survival stories, social commentary, or films that explore the impact of technology on our lives.

4. Dark Hole: A Mutated Horror with a Sci-Fi Edge
Dark Hole ventures into a unique territory within the zombie genre, incorporating elements of science fiction and mutated horror. The story revolves around a mysterious dark smoke emanating from a sinkhole that transforms humans into monstrous creatures. Lee Hwa-sun, a detective whose husband was murdered, travels to Mujishi in search of his killer. However, she soon discovers that the town is plagued by these mutated humans, driven mad by the dark smoke.
Dark Hole distinguishes itself through its unconventional take on the zombie outbreak. The dark smoke acts as a catalyst, triggering latent aggression and transforming individuals into violent, monstrous versions of themselves. The series explores the psychological effects of the smoke, blurring the lines between humanity and monstrosity.
The series also delves into the mystery surrounding the dark hole and its origins. As Hwa-sun investigates, she uncovers a conspiracy that threatens to engulf the entire region.

5. Happiness: A Pandemic Thriller with Social Commentary
Happiness takes a more grounded approach to the zombie genre, focusing on the social and psychological impact of a fictional infectious disease. Set in a near-future South Korea, the series follows Yoon Sae-bom, a tactical agent, and Jung Yi-hyun, a detective, as they navigate a world grappling with a new infectious disease called “Ritz.” This disease turns people into bloodthirsty monsters, but only during periods of intense thirst.
The series unfolds within a newly constructed apartment complex where social strata and pre-existing tensions are amplified by the outbreak. Sae-bom and Yi-hyun, who are in a contract marriage, must protect themselves and their neighbors from both the infected and the societal breakdown that ensues.
Happiness explores themes of class inequality, social paranoia, and the lengths people will go to in order to survive.

The characters are well-developed and relatable, and the performances are strong. Happiness is a thought-provoking and suspenseful series that offers a timely and relevant commentary on contemporary society.
